scripts/decode_stacktrace.sh: guess path to vmlinux by release name
Add option decode_stacktrace -r <release> to specify only release name. This is enough to guess standard paths to vmlinux and modules: $ echo -e 'schedule+0x0/0x0 tap_open+0x0/0x0 [tap]' | ./scripts/decode_stacktrace.sh -r 5.4.0-37-generic schedule (kernel/sched/core.c:4138) tap_open (drivers/net/tap.c:502) tap Signed-off-by: Konstantin Khlebnikov <khlebnikov@yandex-team.ru> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Cc: Sasha Levin <sashal@kernel.org> Link: http://lkml.kernel.org/r/159282923334.248444.2399153100007347838.stgit@buzz Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
